SEABROOK — Aaron Desjardins, the Epping man accused of murdering his ex-wife, Amanda Warf, was ordered held without bail at his arraignment Wednesday.

Desjardins did not speak during a hearing that lasted about five minutes in Seabrook Circuit Court, nor did he enter a plea. He was arraigned on a single first-degree murder charge in connection with Warf's death shortly after 1 p.m.

Warf's body was found inside an abandoned concrete plant in Exeter on Thursday, March 7. Firefighters found her remains on the second floor of the building after it caught fire in the morning.

An autopsy conducted last week revealed Warf died from “incised wounds” to her neck, according to the state's chief medical examiner, who has ruled the death a homicide.

Senior Assistant Attorney General Susan Morrell, the prosecutor overseeing the homicide investigation, said Wednesday it would be fair to characterize the fatal wound as a "horizontal cut" across Warf's neck.

Desjardins appeared to emerge as an early suspect. Homicide investigators searched his home Sunday evening and again on Monday. Authorities from the state fire marshal's office were also present at the scene.

In an interview with Foster's Sunday, Desjardins claimed he had nothing to do with his ex-wife's murder. He was then arrested on Tuesday.

Amanda Warf's mother has been named to the list of potential witnesses in the case, Morrell said during Wednesday's hearing. Desjardins has been ordered to have no contact with her as a result. His current wife, Sarah, and his sister have also been named as potential witnesses.

Desjardins is next scheduled to appear in court in Brentwood for a probable cause hearing on March 22 at 10 a.m.
